BrianG,
The reference Vref speed is what you are calling Vth. If the chart says the Vref for 220,000 pounds is 130 KTS that is in landing config with gear down and flaps 40. You noted the flaps 40 setting is Vref + 10 or Bug +10 so you should be landing at around 140 KTS. The pitch of the nose on approach is about 3 to 5 degrees. Make sure you are sitting high enough by using SHIFT+ENTER to raise up in the seat. You should be able to see most of the HSI and the nut that holds the windshield wiper.
First screen capture, too low in the seat.
Better seat position.
